K-Gear GA43 - 4 x 750W 4-Channel at 4-Ohm Class-D Power Amplifier with Built-in DSP in Black Finish

The K-Gear GA43 is a powerful 4 x 750W 4-channel Class-D power amplifier, designed to deliver high-efficiency audio with precise control for demanding environments. Equipped with a Powersoft power module and an integrated DSP processor, this amplifier is capable of delivering 750W RMS per channel at 4Ω or 2x1500W at 8Ω/100V, making it perfect for large, complex audio setups such as in touring events, auditoriums, transportation hubs, houses of worship, stadiums, theme parks, and nightclubs. Its modular design allows up to three GA43 units to be installed within just 2 rack units when using the G-RACK accessory, providing a compact yet formidable solution for installations requiring powerful sound across multiple channels.

The GA43 offers remote programmability and full DSP control through Powersoft ArmoníaPlus software via Ethernet, enabling users to make precise adjustments to audio parameters remotely. The amplifier's 4IN-4OUT configuration supports versatile routing, while the built-in DSP offers customizable EQ, limiting, and crossover settings. It includes four user-adjustable presets that can be stored and recalled using a physical button on the rear panel, allowing for quick adaptation to different environments or audio requirements. The GA43 is also designed with a dedicated preset for 70V or 100V speaker lines, adding further flexibility for installations utilizing high-impedance speaker configurations.

To ensure reliable operation, the GA43 is equipped with comprehensive protection features, including thermal protection with power limiting and thermal shutdown, short-circuit and overload output protection, stationary high-frequency protection, peak limiter, RMS limiter, frequency-dependent RMS limiter, and clip limiter. Constructed from durable stainless steel with a sleek black finish, the GA43 is built for both aesthetic appeal and endurance in professional setups. It operates within a wide 85-245 VAC range, enhancing its adaptability across different power conditions, and its compact size (5.7 x 3.54 x 16.5 inches) and weight of 7.94 lbs make it easy to integrate into any rack-mounted installation.
